VizieR Online Data Catalog: Vetting asteroseismic Δν measurements (Reyes+, 2022)
Abstract
The SYD pipeline is run on all the K2 power spectra from Campaigns 1-8 and 10-18 corresponding to 47683 time series (from 45132 unique targets) that were deemed to potentially show oscillations by the neural network detection algorithm from Hon et al. (2018ApJ...859...64H). No significance testing or other form of vetting was performed on the resulting νmax and Δν results from this SYD run. Hence, by construction, we expect a large fraction of Δν values to be incorrect. Fewer than 20000 stars are known to actually show oscillations with reliable seismic results for both νmax and Δν in the K2 GAP sample (Zinn et al. 2021, in prep., arXiv:2108.05455). The vetting method that we now implement as part of the SYD pipeline is therefore our neural network classifier, and the resulting vetted SYD values are listed in Table G1.
Our vetted results and the probabilities given by the network after running it on original samples from the five pipelines are listed in Table G2, broken down by campaign. (2 data files).- Publication:
